Pine wood

We cut a carved beam from a trunk of pine 6 m long and 35 cm in diameter. The beam has a cross-section in the shape of a square. The square has the greatest area. Calculate the length of the sides of a square. Calculate the volume in cubic meters of lumber.

Correct answer:

a =  24.75 cm
V =  0.3675 m3

Step-by-step explanation:

D=35 cm L=6 m  D = 2  a  a=D/2=35/2=24.75 cm
A=a m=a:100  m=24.7487:100  m=0.24749 m V=A2 L=0.24752 6=0.3675 m3
